It's a typographic joy with all its whitespace and judicious mix of fonts.

Sparrow 66
Black Sparrow Press, March 1978

It features a poem by Gerard Malanga "This Will Kill That". As with many paratextual matters, not sure if the frontispiece is meant to be part of the poem. It can certainly stand alone.

The triangle, hemicircle and the square remind me of the three base shapes of kindergarten gifts. [See Inventing Kindergarten by Norman Brosterman: sphere, cylinder, cube].

The last page turns from architecture to mirrors. Floating on the page are two simple but forceful lines:

This will kill that.
You are that.

Challenging to evade the threat. Not however impossible. Casuistry to the rescue.

The "you" is part of the "that" if one takes as referent of "that" to be the two lines on the page. The day will arrive when this is indeed the case. And on that day "this" will die. Of course the dead this may be made more lethal by its dying.
